Overview of this book

Python is a multi-domain, interpreted programming language. It is a widely used general-purpose, high-level programming language. It is often used as a scripting language because of its forgiving syntax and compatibility with a wide variety of different eco-systems. Python GUI Programming Cookbook follows a task-based approach to help you create beautiful and very effective GUIs with the least amount of code necessary. This book will guide you through the very basics of creating a fully functional GUI in Python with only a few lines of code. Each and every recipe adds more widgets to the GUIs we are creating. While the cookbook recipes all stand on their own, there is a common theme running through all of them. As our GUIs keep expanding, using more and more widgets, we start to talk to networks, databases, and graphical libraries that greatly enhance our GUI’s functionality. This book is what you need to expand your knowledge on the subject of GUIs, and make sure you’re not missing out in the long run.

Passing queues among different modules


In this recipe, we will pass queues around different modules. As our GUI code increases in complexity, we want to separate the GUI components from the business logic, separating them out into different modules.

Modularization gives us code reuse and also makes the code more readable.

Once the data to be displayed in our GUI comes from different data sources, we will face latency issues, which is what queues solve. By passing instances of Queue among different Python modules, we are separating the different concerns of the modules' functionalities.

Note

The GUI code ideally would only be concerned with creating and displaying widgets. The business logic modules' job is only to do the business logic.

We have to combine the two elements, ideally using as few relations among the different modules as possible, reducing code interdependence.

Note

The coding principle of avoiding unnecessary dependencies is usually called loose coupling.
